Quadro K600 graphics card at Newegg - $39.99

Does it specifically say in the menu HDR ? I don't think Ultra Deep Color is the same as HDR.
What is the model year of the TV ?

LG 55UJ632T

do I have a faulty adapter or hdmi cable?

I just noticed this in the Xlent product description.

Notice: If display device is with HDMI 1.4, our adapter will only support 4K@30Hz; adapter's chip is Single Streamed, which means if PC's Graphics Card is Multiple Streamed, the resolution will only be up to 4K@30Hz;

If you can still return it I would try the Plugable adapter. $13.95 with a coupon on Amazon right now. Great deal.

You could also try a straight DP to DP cable to a 4K PC monitor and see if the one you have works there. That's what these quadros were designed for, not for modern 4K televisions.

Unfortunately I do not have a 4K monitor with DP

The other limitation of the K600 is the 1GB of Vram. That's fine for a single 4K PC monitor. With a 50" TV it would be best to have a couple of GB of Vram to push 4K at 60 Hz. TVs are all about fast movement, especially with sports. PC monitors generally have a lot less going on.

This is the description for the related NVS 510. It also uses MST.

Drives four DisplayPort enabled digital displays at resolutions up to 3840 × 2160 at 60 Hz with reduced blanking, when connected natively using the 4 DisplayPort connectors on the NVS 510 graphics card.

DisplayPort Multi-Stream Topology (MST) Technology: Supports various combinations of display resolutions and number of displays when using DisplayPort multi stream topology technology.

Here's the only two active adapters I've seen that support HDMI 2.0b which is required for use with an HDR TV. They are made by Lenovo and Club3D respectively.

Again, the graphics card you use must be DP 1.4 for these to work with an HDR TV. An RX 560/70/80 should work.
It is best to avoid the XFX brand RX 560s for the best results.

Hi all! I moved my RX 580 to a gaming pc and bought 2X k600 Quadros for my custom mac (cause i use 4 monitors). With one card it works out of the box, no changes needed, but when i install the second k600 i get a black screen after the apple logo loader.
Is there any settings i need to be changing for the two cards to work?
I use the first PCIe x8 for the second card cause the second X16 is used by the NVme adapter, could this be a thing?
cheers!
